Power Interlock Switch
Some PolyTherm Chiller/Heater systems are optionally
equipped with a panel-mounted disconnect switch
installed on the outside of the power distribution panel.
The disconnect switch must be turned to the off position
before the panel can be opened for service.
Single Point Connections
For systems with single point power connections, detach
the power cable on each module by cutting the wire tie
installed for shipping.
1. Uncoil the power cable and snake it through each
module to reach the power distribution panel.
2. Feed the taped end of the cable through the round
opening on the extreme left of the power distribution
panel.
3. Remove the tape and connect and tighten the cable
ends to the breaker corresponding to the module
number being connected. (For example, connect the
cable for module #8 to the breaker labeled #8.)
4. Connect the green ground lead to the ground lug at the
base of the enclosure.
5. Do not secure the ground wire until all of the ground
wires are connected to the ground lug and then each
can be tightened.
6. After connection, secure all power cables with
standard wire ties.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury. Disconnect all electric
power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized.
